Answer:
12.7
Step-by-step explanation:
If this is a right triangle then you just have to use pythagorean theorem. If fifteen is the hypotenuse then fifteen squared minus eight squared will give you x squared. Fifteen squared is 225 and eight squared is 64 so you subtract 64 from 225 to acquire the number 161. The square root of 161 is not exact but when rounded it is 12.7

Answer:
20 measured and 10 used
Step-by-step explanation:
Total number of participants is given as n = 10.
Number of treatment conditions = 2
Total measurements is therefore 2 × 10 = 20
Therefore, in total, 20 scores will be measured in the given study.
Now there are two samples and for each sample, for each sample we need to calculate the mean = Sum of value(measures)/Number of measures
mean = Sum of value(measures)/10
Therefore, we are going to have 20 measured and 10 used to calculate the sample mean and the sample variance.
